Experimental and numerical investigation of fracture in double-edge notched steel plates

Primary tabs

Knockaert, R Doghri, Issam [UCL] Marchal, Y. Pardoen, Thomas [UCL] Delannay, Francis [UCL]

Double-edge notched (DENT) steel plates were pulled until complete fracture and several experimental observations were made (using profilometry and scanning electron microscopy). The essential work of fracture (EWF) model was found to be well verified. Numerical simulations - up to the maximum load only - of some experiments were performed using the finite element method (FEM), and incorporating geometric and material non-linearities (large deformation elasto-plasticity). Some experimental measurements were compared with the corresponding numerical computations and excellent agreement was found.
